Answer from: cupkakekawaii45

Explanation:

I don't know exactly, but I think it is a suspension because of all the macromolecules and other things in the blood. It could also be a solution because blood dissolves things like salt, minerals, vitamins, and lots of other things. I would pick one of those two.

Answer from: carterkelley12oz0kp1

The correct answer is C. a suspension

Explanation:

Suspension is a mixture of solute and solvent in which the solute particles do not mix with solvent and get pellet down if left undisturbed.

So in the case of blood, blood cells do not dissolve in it and these cells settle down when left undisturbed for some time. Salts, proteins, and serum also settles down with blood cells.

But blood is a mixture with quality of all three medium solution, colloid, and suspension so it is hard to say that blood is only suspension. Colloidal suspension is another word that is widely used for blood.
